I'm currently using Avid Juicy carbons on an Ellsworth Epiphany and am not impressed. They are very noisey, even when dry and don't modulate as well as I hoped and expected. I'm looking to upgrade into the K24 or Mono Minis. I plan on running 180 / 160 rotors. The LBS is pumped on Hope (and they know how to ride) but its hard to ignore all the strong K24 praise on this forum. Anyone had an opportunity to compare both brake systems? Thanks for your feedback.
